RE: Elete 4500
The pack is Atleast, 2 years old maby even more like 2 1/2 years. The packs have never gotton above 8.8 volts and they always get consistant run time. My first charge on them I got 8.6, now I occasionaly get 8.8.
Hold on to those packs. They might have some life in them. Waych the charge mAh in time you charge along with the temps. If you have successive increases in the mAh each charge and temps stay below 120.....you're OK.
I've also heard some of the pros do multiple charge/discharge using their chaarger (not dischaarge tray or lights) to wake thee packs up. If you don't have a charger/dis....just dischaarge them in the boat. And have fun.
What kind of tempss are getting on the packs after a run and whaat size prop are you using? These are critical to the condition of batts/setup. Let us know in the Supertune Youur SV thread.
